Message Waiting Indication
You may configure the parameters shown in the graphic and explained below:
Transfer type: The following options are available:
With consultation call (Call Deflection): The call is transmitted automatically.
With consultation call (Explicit Call Transfer): After the transfer to the destination party, the
channel is freed. The transfer may be announced or unannounced.
With consultation call via tromboning: The call transfer is emulated. Two B-channels are
blocked during the call transfer.
Complete transfer
in state:
The blind call transfer is typically handled via an implicit call to the transfer destination. Once this
call reaches the state specified via the option Invoke Call Transfer in state, the call transfer is
completed. Default setting is Connected. If the calling party should hear the ring back tone from
the transfer destination, this parameter must be set to Proceeding or Alerting.
Use same channel
for implicit call:
The B-channel used for the primary call is used for the consultation call as well. This requires that
the option Hold primary call before transfer is enabled. For Dialogic
®
Diva
®
Analog Media
Boards and protocols using inband signaling, this option must be enabled.
Primary call on
Hold before
transfer:
Select this option to place the primary call on hold before a call to the transfer destination is
initiated.
Use tromboning if
transfer fails
(needs two bearer
channels):
Select this option if the Call Transfer should be emulated in case it could not be transferred with
Call Deflection or Explicit Call Transfer.
Use this controller for
MWI:
The controller to use for MWI needs to be connected to a PBX port, which allows for updating
of the message waiting indication.
Controlling user
number:
A PBX typically requests an authentication to allow for updating of the message waiting
indication. This authentication is done by a Controlling user number. The administrator of
the PBX can provide this number.
Controlling user
provided number:
The Controlling user provided number (CUPN) is the ISDN number provided by the
controlling user, e.g., the ISDN number of the originating user of the indicated message. Few
PBXs (e.g., Nortel) require the CUPN. The administrator of the PBX can provide more
information.
